Dataset & Data Search
Dataset search tools help you find open data, research collections and public records from many fields. Listings include catalogues, repositories and portals from governments, universities, labs and open projects. Some cover one subject closely, such as genomics, climate or satellite imagery, while others gather datasets across many areas and add filters, previews and download notes. Compare a few side by side and look at the licence, the update date and the file formats offered, since two portals that look alike can carry very different terms. Check whether a catalogue links to the original data or hosts its own copy, because the source usually explains provenance and any limits on reuse.
cathdb.info
CATH is a free online database providing information on evolutionary relationships of protein domains, developed by the Orengo group at University College London. Structures from the Protein Data Bank are split into domains and classified by class, architecture, topology and homologous superfamily. Gene3D adds sequence data from UniProtKB and Ensembl, assigning domains to superfamilies.
atom.curtin.edu.au
CCC Data Base is a database of convergent close-coupling cross-section data for atomic targets, created by Yuri Ralchenko and Igor Bray. It lists electron-impact data for several elements and ions, positron-impact data for several targets including H-like ions, and proton-impact data for helium. Molecular targets are directed to a separate site.
